MACHINE FOR. TURNING IN THE EDGES OF THE COATING-PAPER 0F BOXES To all whom it may concern;

Be it known that I, VVILLIAM G. Sononr- TLE, a citizen of the United States, residing.

skilled in the art to which it appertains to make and use the same.

This invention. relates to machinesfor turning the edges of the coverin paper of paper-boxes inwardly over the e ges of the x box or cover and compressing it against the inner faces of the Walls of the box or cover,

said operation following immediately after the application of the coveringpaper and before the adhesive material applied thereto has dried. v

The object of the present invention is to provide mechanical means for turning the covering paper over the ed e of the box and f causing it to adhere to t e inside of the box, and I accomplish this object by means of the mechanism as hereinafter described, the novel features being pointed out in the annexed claims.

In the accompanying drawings illustrating this invention and forming a part of this specification, Figure 1 represents a side elevation of a machine constructed in accordance with this invention.

It has been customary in machines of this class, so vfaras I am aware, to move the edge of the box against-the brushes or other turning-in devic s, by causing the box to rotate about a fixed axis. the box are circular the turning-in devices can be readily arranged in the path of the rotating box, but when the boxes are polygonal, mechanism is required to adjust the brushes to the path of the box, sides. By means of the present invention I maintain the turning-in brushes in a fixed posit-ion, and provide mechanism for controlling the movement of the box so that each of its sides is made to move in a straight line past the brushes.- To accomplish this result I impart a series of rotative movements to the box about axes at or near the corners of the box, so that each point in the edges of a polygonal box is made to pass through a given fixed point and be operated upon by the turning-in brushes held in a fixed position.

The machine embodying my present invention comprises therefore the following instrumentalities, rotating brushes held in fixed bearings in proper relation to the sides of the box to act upon the projecting covering strip; means forsupporting a box upon its bottom leaving its edges free to be acted upon by the rotating brushes; means for moving the edges of the box in a straight line past the rotating brushes; means for imparting a rotative movement to the box at each of its corners. 1

So far as I am aware it is broadly new to combine the inst-rumentalitiesenumerated above in a machine for turning in the covering paper upon a polygonal box, whereby each of its sides is moved in a straight line past fixed turning-in devices.

Referring to the accompanying drawings 1 denotes the framework, comprising a table suitably supported, in which is journaled. a driving shaft 2 provided with a pulley 3 and clutch 4, which serves to connect said When the sides of V shaft 2 with'an suitable source of power.

the box to be operated upon. The frame The inner end 0 the driving shaft 2 carries a bevel pinion 5 which meshes with a bevel gear 6 one vertically disposed shaft 7 journaled in the framework, and carrying upon its upper end a friction roller 8 which projects above the table. The shaft 7 carries a spur ar 9 which meshes with spur gears 10 and 11 on vertically disposed shafts 12 and 13, journaled at their lower ends in swinging bearings 14 and 1 5, and at their upper ends in journal boxes 16, attached to a guide member 17 which is horizontally movable in a slotted guide 18 rigidly secured .to the framework. The guide member 17 carries a screwthreaded rod 19 which passes through a downwardly extending flange 21 on said guide 18, and also through an open-' ing in a lever 22 pivotally secured at its lower end in and between two projections 23 at the lower end of the flange 21.

The screwthreaded rod 19 carries a nut 24 on its free end which serves as a collar to engage the lever 22. A s iral compression' spring 25 is interpose between the guide member 17 and the flange 21, and the lever 22 serves as a means for drawing said guide member toward said flange against the action of the spring 25. The upper ends of the shafts 12 and 13 carry friction rollers 26 and 27 which project above the table and are in the same horizontal plane as the roller 8.

Between the rollers 8, 26 and 27, as illustrated in diagram in Fig. 9, a-frame 28 is held which is moved by the rotation of the rollers, said frame being horizontally disposed and adjustable in size, and provided on each of its four corners with a corner plate 29 adapted to receive the corners of 28 consists of four L-shaped members having arms of different lengths, with two diagonally opposite members provided adjacent to the lower faces of their arms with extensions 30 having teeth and forming racks, said extensions being of less width than the arms of said members and flush with the outer edges thereof. The other two diagonally opposite members are provided on their lower faces with toothed flanges 31 which mesh with the racks 30 and serve to hold all the members firmly in the posit-ion to which they are adjusted, the interlocking racks being clamped together in any suitable manner, as by bolts 32 passing through slots .33. The rollers 8, 26 and 27 engage the inner and outer edges respectively of the racks 30 and flanges 31, and thereby cause said frame to travel peripherally, the corners of the latter being rounded to permit the frame to turn at each corner. As the frame 28 which supports the box to be operated upon is moved by the rotation of the rollers 8,- 26 and 27, each side of the frame will be moved in a straight line, and the frame will be given a rotative movement at each of its corners as the rounded corners of the frame pass between the rollers. The corner plates 29 which receive ,the box to be operated upon are arranged to hold the sides of the box in a vertical lane parallel with the axis of rotation o the roller 8, and 'as the rounded corners of the frame pass between the rollers, theroller 8 forms the fulcrum about which the frame turns. The rollers 26 and 27 are held in a yielding contact with-the frame by the spring 25 in order to permit the corner of the frame to pass between the outer rollers 26 and 27 and the inner-roller 8.

Pivotally secured at one end to the framework is a lever 34 which is provided with a downwardly extending deflected arm 35 which engages one member of a clutching mechanism 4. Near its free end the lever 34 passes through a vertical guide in the framework and is arranged to be engaged by a vertically disposed trip lever 36, pivotally secured to the frame about midway between its ends and provided at its lower end and upon its outer face with a recess 37 adapted to receive the lever 34 and hold it in a depressed position against the action of a sprlng 38 connect-ing the pivoted lever with the rigid framework. A second lever 40 is pivoted at one end to the framework with its free end adapted to engage the lower end of the trip lever 36. Attached to the lever 40 is a short rack 41 which is adapted to mesh with a worm 42 carried on the vertical shaft 12. The rotation of the worm 42 engaging the rack 41 causes the free end of the lever 40 to be raised until the rack 41 is carried out of enga ement with the worm. A horizontally dlsposed rod 43 is providedwith a T-shaped end which is held in contact with one s1de of a lever ,40 by means of a spiral compression spring 44. The tension ofthe spring 44 presses the T-sh-aped end of the rod 43 against the side of the lever 40 in order to hold its rack 41 in engagement with the worm 42 during the limit of movement of the lever. I

Secured to the inner face of the trip lever 36 and movable longitudinally with relation thereto is a plunger 45 having at its lower end a longitudinal slot 46 through which a bolt 46 passes into the'free end of the lever 40. Held in plunger 45 and bearing against the bolt 46 is a spiral spring 46 in-order to,

hold said plunger normally at the upper limit of itsmovement relatively to the lever 40. When the lever 40 is raised by the engagement of its rack 41 with the worm 42 the upper end of the plunger 45 is moved above the table into the path of the frame 28 as the latter completes a revolution, causing the upper end of the plunger 45 to be thrown outwardly and rocking the trip lever 36 on its pivot to release the lever 34 which is imtrip lever36 is turned to release the lever 34,

as above described, it moves the free end of the lever 40 against the action of the spring 44, thereby carrying the rack 41 out of alinement with the worm'42, allowing the lever 40 and plunger 45 to be immediately moved by gravity to the lower limits of their movement, where they will remain until the free end of the lever 34 is again depressed. The downward movement of the lever 40 is determined by a vertically adjustable slotted stop plate 48 secured to the framework by a bolt 48*.

The covering paper is a plied to the box before it is fed to the maciiine and projects beyond the upper edge of the side walls of the box usually from t" to 4 which must be turned inwardly and downwardly and compressed smoothly against the inner faces of the side walls of the box before the adhesive material applied to the covering paper has been allowed to dry.

The covering paper is frequently tender by reason of its thinness and its moist condition, and it becomes necessary that it should be manipulated so as t0.preventits being turned, and at the same time the operation must be completed with great rapidity. To effect this I turn the paper inwardly by means of one brush, and downwardly by means of another brush, which also serves to compress the turned in covering paper against the inner sides of the box, said a brushes being revolved at high speed and being constructed and arranged to produce the desired result at the corners as well as on the straight sides of the box.

The brushes 49 and 50 are carried upon the ends of shafts 51 and 52 journaled inbearings 53 and 54 formed upon a horizontal bracket or plate 53*, which is integral with a collar 55 longitudinally adjustable on a vertical standard 56, which is supported on the lever 34, and on a compression spring 57 bearing at its lower end upon a bracket 58 projecting from the framework, and in which bracket the vertical standard 56 is capable of longitudinal movement. The vertical standard 56 is connected with the lever 34 by means of a link 59 which is pivoted at one end to the lever 34 and at its opposite end to anarm 60 rigidly attached to the vertical standard 56. The spring 57 is interposed between the bracket 58 and the arm 60.

The shaft 51 carrying the rotating brush 49 lies in a horizontal plane but is placed at an oblique angle to the side of the box as it passes beneath the brush, so that the bristles of the brush travel over the paper to be turned in, in substantially the same direction as that in which the box moves, but at an angle thereto, so that the planes in which the bristles rotate intersect the planes of the walls of the box and, owing to the eater surface speed of the brush, the pro ecting edge of the covering paper will be turned or deflected inwardly toward the middle of the bbx by the brush 49 and carried into the path of the brush 50. The brush'49 is preferably slightly tapered, so that the bristles will first engage only the extreme free edge of the covering paper, and the next adjacent longer bristles will engage the covering paper nearer the walls of the box, thereby making the turning over operation gradual.

It frequently happens that the projecting edge of the covering paper is turned backward, so that when the box is placed in the carriage or frame 28, and the brushes are brought into operative relation thereto, the latter cannot catch the free edge of the covering paper, and to overcome this difiiculty I provlde a spring finger 49 which is secured at one end to the horizontal plate or bracket 53, with its free end depending normally in the path of the edge of the box, the extreme free end being curved slightly outwardly, and the portion immediately above the extreme free end being straight and vertically disposed, so that the outer faces of the walls ofthe box will bear against the spring finger. Above said straight portion the finger is bent to overhang the upper edges of the box forming a loop terminating at the point of fastening of said'spring finger to the plate or bracket 53 When the box is placed in position on the spring finger 49 and as the plate 53 is lowered to bring the brushes into operative relation to the box the overhanging loop portion of the spring finger 49. will turn the free edge of the covering paper inwardly, thereby bringing'the edge into the path of the brush 49, by which it is further turned into the path of the brush 50. The pressure of the spring finger 49 against the outer side of the walls of the box will serve in part to prevent the walls of the box from yielding to the pressure exerted by the brush 50.

The shaft 52 is inclined downwardly at the end carrying the brush 50,and lies in a like and the bristles are disposed substantially tangential to the hub, and inclined The tangential disposition of'the bristles.

rearwardly from the radial lines relatively to the direction of rotation. The bristles ofthe brush 50 are also disposed at a sligh-t'inclina'tion to the plane of the hub, so as to give the brush a dished eflect, the object being'to cause the'bristles to travel vertically over the edge portion of the covering paper and brush the same constantly downward.

- 50, I provide a roller 61 mounted on the end of an arm 62 secured to the plate 53 and bearing against the outer facesv of the walls of the box, as represented in Figs. 1, 2 and 3; An arm 62 is secured to the plate 53 and upon its free end it carries a downwardly.

extending foot piece'62 ,-the lowerend of which is provided with a caster wheel 62,

which is arranged to bear on the bottom of the box and serveto hold the same downward against the box supporting carriage, and prevent the tipping or canting of the box.

Integral with the collar is a horizontally disposed sleeve 63 which supports a rod 64' carrying at one end twoloose pulleys 65 and 66, which are rigidly attached to each other. The opposite end of the rod 64:

is secured in a sleeve 67 which is vertically adjustable on an upright standard 68. In a .lower plane than the sleeve 63 and on the opposite side of the collar 55 is a journal 69 supported by "the plate 53 and supporting the two pulleys 70 and 71. The brush shaft 52 is provided with a ulley 7 4: and the brush shaft51 with a pu ley 76. Idler pulleys 77 and 78 are supported on a spindle 79 held by a collar 80 which is adjustably supported upon a vertical standard 81, held by a collar 82 attachedto the upper end of the upright standard 56. The collar 82 has a projecting lug 83 through which loosely passes an adjusting screw 84 provided with a hand wheel 85 and a collar 86 which holds the adjusting screw from longitudinal movement in the bracket 83-. The adjusting screw 84 passes loosely through I two projecting lugs 87 on the collar 55, and between the lugs 87 is a nut 88 engaging the'screw 84. By the adjusting screw 84 the collar 55 and plate 53 carrying the bearings for the rotating brush'shaft is raised and lowered on the standard 56 to vertically adjust the position gt the brushes relatively to the height of the As previously stated the standard 56 is pivotally connected by a link 59 with the lever 34, so that when the lever 34 is depressed to throw in the clutching mechanism, the standard 56 will be lowered at the same time and bring the brushes into operative position relatively to the box. When the love as mass and raised by a. Sta 38, the tandard 56 and the parts carried brushes out of operativerelation to the box. When a set of boxes ofdifi'erent depth are to be operated upon, the position of the brushes on the standard'56 may be adjusted to correspond by means of the adjusting also be adjusted in a horizontal plane in order to regulate the pressure exerted by the covering'paper to the inside of the box. The horizontal adjustment is accomplished as follows :The upright standard 68 is mounted on the free end of an arm 89 pivotally securedto the table, and the standard passes through a slot 90 in the plate 53, serving to hold the plate 53 and standard 56 against rotation. A lug or projection 91, Fig.8, is provided at the edge of the table and carries a screw 92which enters a screw 89. The screw 92 is held from longitudinal movement'in the projection 91 so that the swing-the lever 89 together with the .upright standard 68 and plate 53*. The idler pulleys and the pulleys attached to the rotatin shafts are preferabl scored, and have suita le belt connections y which the rotatable shafts. are driven.
